The third in the Ziba Mackenzie thriller series. I haven’t read the first two books but it can be read as a stand alone, although the ending is left on something of a cliffhanger. A serial killer known as the PRK (Pink Rose Killer) is having a killing spree in London. Meanwhile another notorious mass murderer incarcerated in HM Wakefield Prison seems to know the killer’s real identity and is predicting what they’re going to do next.

I read this story via the Pigeonhole app where the book is split into ten daily staves and I looked forward to receiving each instalment. I’m not a fan of serial killer thrillers but I was quite gripped by this one. It’s fast paced with some great characters. There is a puzzle to solve and coded clues to decipher which I enjoyed. It’s a cat and mouse game with a race against time sort of tale which kept me turning the pages. There’s not much more I can say without giving the plot away, so overall a it’s a good thriller which will appeal to fans of Thomas Harris and Robert Bloch. ( )
